* Patented Jan. 18, 1944 My invention 'relates t articlesrr'ianuf'actureci by what is commonly known asfth'e dipping process. It'may ybe used "for various articles corn`-I posed `oi any suitablematerial foi" s cong'ealable' lution and deposited ,on a form.l

Aliquid form or capableof being reduced to 4afso-v Myv invention relatesparticularly to surgical 7 devices as finger-cots, nipp1es', ,rubber'gloves, n-

ger-stalls, prophylactics,V catheters, sheaths or the like, `made from aliquidlatex compound or rubber cement or any other suital:-1e`'rnaterial.`

The surface of rubber and related material usually used for sucharticlesoiersa ccmparatively high resistance to an introduction into abody opening.` Suchresi'stance entails the clar 1l`.;1i

ger' of irritation of body tissues andof damage to theintroducednger-stall or the like since the material used for sucharticles Ais very thin l and sensitive.` Various suggestions have been vbeen made to secure a smooth sliding eifect. For,

instanceit is known' to treat th'e surface 'ofthe article with.substances whichnquickly 4swell if c brought in contact with moisture`and make the surface of the rubberor'` so like slippery. ,How-

ever, the use of such` quick swellingj substances has'th'e disadvantagethat the surface becomes slippery only when sumcient moisture isrpresentand after the surface has been broughtinto ccntactwith it. l Cor1sequent ly,the resistance applied toan introduction is not reducedbytheuse of such swelling substances at` the momentvof penetration. An objectof -my bricant for making the surface. oi.' surgical devices such asringer-cots,v prophylactics and :the

invention is to 1 provide a lu l,

like slippery before introduction `into'va body opening. withoutrequiring' a preceding contanti-v with moistureand to protectsuchlubricantby, a Vsanitary cover which canA be easily removedVl`rpsrtlyor entirely whenthe articleis to be usedz Another object of myinvention-lis to .combine surgical devices such 4as linger-stalls,prophylsctics andthe like and {.a lubricantxfor:makingr` the surface 'ofthesearticles slippery .before in.l 145 traduction into a body openinginto alunit'vby env closing the lubricant and, ,the articles into acommon container; In this container-I separate said lubricant and saidarticlesby aneasilyremovable partition, sheet which' protects saidlubricant against any unsanitarycontact until `the lubricant isto beused. I provide the lubricant either on the bottom or atthe top ofsaidcon-A tainer. v

Another object of Amy invention isto'combiney at least one surgicaldevice such as a finger-stalL.
